[image]Center is at Latitude 30 Degrees South, Longitude 210 Degrees - NASA
Center of the orthographic projection is at latitude 30 degrees S., longitude 210 degrees. Toward the top, the lowland plains of Elysium and Utopia Planitiae are separated from the darker heavily cratered highlands by a broad escarpment. The far bottom left is marked by the large light-colored ancient Hellas impact basin. The permanent south polar residual ice cap is located near the bottom.

The coordinates of the Lambert azimuthal equal area projection are latitude 90 degrees N. to 90 degrees S. and longitude -180 degrees to 0 degrees. The north polar residual ice cap of the Planum Boreum region, which is cut by spiral-patterned troughs, is located at top. The upper part is marked by large depression, Isidis basin, which contains light-colored plains. The upper part also includes the light-colored smooth plains of Elysium Planitia and dark plains of Vastitas Borealis...

Neptune's bright crescent taken in six filters (from bottom to top: UV, violet, blue, clear, green, orange) on 31.3 August 1989. The images were shuttered in temporal order: violet, blue, UV, clear, green, orange. These images how the bright core of D2, the south polar feature, and the symmetric structure immediately surrounding the south pole. The relatively high contrast of the features in these images indicates that they extend above most of the scattering haze and absorbing methate gas in Ne...

[image]MOPITT First Light Radiances from March 3, 2000 - MOPITT Instrument Team, Canadian Space Agency
MOPITT measures radiances in several channels to determine the amount of carbon monoxide (CO) and methane in the atmosphere. Channel 1 Difference radiances, shown here, are sensitive to the temperature of the earth's surface, the temperature of the atmosphere, and the amount of CO Of these, the first two effects dominate. Thus, we see red colors, indicating high radiances and high surface temperatures from the subtropical deserts (Sahara, Arabian, Rajastan and Kalahari)...

[image]Icefall on the Lambert Glacier - Image provided by the Satellite Systems Branch This image is part of the ongoing Landsat series.
The Lambert Glacier in Antarctica is the world’s largest glacier. The focal point of this image is an icefall that feeds into the Lambert glacier from the vast ice sheet covering the polar plateau. Ice flows like water, albeit much more slowly. Cracks can be seen in this icefall as it bends and twists on its slow-motion descent 1300 feet (400 meters) to the glacier below.This image was acquired by Landsat 7’s Enhanced Thematic Mapper plus (ETM+) sensor on December 2, 2000...

Part of the ongoing research into polar ice trends encompasses evaluation from sophisticated computer models. At the Geophysical Fluid Dynamics Laboratory at Princeton University, run by NASA's sibling agency, NOAA, researchers modeled a 5,000 year period to see how polar ice might behave over time depending on several different variables. This visualization shows a 120-year slice of that complete model, essentially offering a research window on to experimental processes that require longer time...

*Description*: This is a color polar view of the north polar region, showing the location of the storm relative to the classical bright and dark features in this area. The color composite data (410, 502, and 673 nm) indicate that the storm is fairly dust-free and therefore likely composed mostly of water ice clouds. The bright surface region beneath the eye of the storm can be seen clearly. This map covers the region north of 45 degrees latitude and is oriented with 0 degrees longitude at the bo...
